Neels Hofmeyr 3c89a6bce6 msc: overhaul voice call testing
* Semantic:

We don't really know which side the MSC first creates a CRCX for. Instead of
assuming that the RAN side is always CRCX'd first, simply handle a "first" and
a "second" CRCX, not making any assumptions which is for which side.
Notably, there still are quite a few places assuming which CRCX corresponds to
the RAN/CN side, but the changes are sufficient to still pass the tests when
osmo-msc swaps the CRCX order; sometimes for slightly obscure reasons, for
example because it doesn't matter that the wrong port number is returned during
a subsequent MDCX... Cleaning up the rest is still todo for later.

Remove code dup from call establishing code, particularly for MGCP.

Use f_mo_call_establish() and f_mt_call() where ever possible, to make all of
the call establishing tests handle upcoming changes in osmo-msc's order of
messages, without re-implementing the changes for each test individually.

The X-Osmux parameter was so far expected to appear in the first CRCX received,
assuming that this first CRCX is for the RAN.  Instead, detect whether X-Osmux
is contained in a CRCX, and reply with an Osmux CID if so, regardless of it
being the first or second CRCX.  Count the number of X-Osmux parameters
received in CRCX messages, and compare after call setup to verify X-Osmux
presence.

Since f_mo_call_establish() can't handle RANAP assignment, a few Iu tests that
worked with the older code dup will break by this patch. This is fixed by a
subsequent patch, see I0ead36333ab665147b8d222070ea5cf8afc555ec.

* Details, per patch chunk:

Change ts_BSSMAP_IE_AoIP_TLA4 to a non-value template, so that we can use a
wildcard for the assigned port number from MGCP (depending on RAN or CN CRCX
first, the RAN port number can be one or the other).

In CallParameters, move MGCP handling instructions into a separate record
"CrcxResponse", and have two of them for handling the first and the second
CRCX, replacing mgw_rtp_{ip,port}_{bss,mss} and mgcp_connection_id_{bss,mss}.

In CallParameters, add some flags for early-exiting call establishment with a
particular desired behavior, for specialized tests.

In CallParameters, use common default values and don't repeat them in each and
every call establishing test.

Set cpars.mo_call := {true,false} implicitly when f_{mo,mt}_call_establish()
are invoked.

Remove CRCX comments implying RAN or CN side, instead just talk of the "first"
and the "second" CRCX.

Implement one common f_handle_crcx() function, which is used by
f_mo_call_establish(), f_mt_call_complete(), as_optional_mgcp_crcx(), and
implicitly uses the first/second CRCX handling.

For Assigment, use a wildcard RTP port so that we don't have to assume which
CRCX was for the RAN side.

In f_mo_call_establish(), insert special case conditions to make it enact
errors at specific times, for individual tests. That saves re-implementing the
entire call establishment (code dup).

For error cases, add expectation of a CC Release message in the call
establishment. This should not apply for normal successful operation, but
because interleave does not support conditionals, add flags
got_mncc_setup_compl_ind and got_cc_connect to break the interleave when
establishing is complete, so that the CC Release is skipped.
A CC Release always breaks the interleave, at whatever time it arrives.

Tests adopting f_{mo,mt}_call instead of code dup:
  f_tc_mo_setup_and_nothing()
  f_tc_mo_crcx_ran_timeout()
  f_tc_mo_crcx_ran_reject()
  f_tc_mo_release_timeout()
  f_tc_mo_cc_bssmap_clear()

Vadim Yanitskiy 36558d9526 library/PCUIF_Types.ttcn: extend RACH.ind with TRX / TS number fields
Since there can be multiple PDCH channels configured on different
timeslots, different TRXes, and BTSes, the PTCCH/U handling code
in OsmoPCU needs to know the exact origin of a given RACH.ind.

Otherwise, it is not known which subscriber originated a given
PTCCH/U indication, and hence it is impossible to send PTCCH/D
Timing Advance notification properly.

Fortunately, we can extend the RACH.ind message without even
bumping the protocol version, because every single PDU has a
fixed size defined by the largest message - INFO.ind. In case
if the actual message payload is smaller, the rest is filled
with a constant padding byte (0x00).

Older versions of OsmoPCU will consider the new fields as padding,
while the messages from older OsmoBTS versions will always have
both fields set to 0x00. Since C0/TS0 cannot be configured to
PDCH, this can be easily detected on the other end.

Harald Welte 619b2a6547 VPCD protocol support (for vsmartcard.git PCD/PICC code)
vsmartcard.git contains an implementation of a virtual card reader
(vpcd) which registers with PC/SC (such as pcsc-lite).  It simply
binds to a TCP port and waits for a TCP client to connect to it,
implementing APDU transfer over TCP.

This code implements the related protocol as a TTCN-3 test port
for Eclipse TITAN, which will enable us to implement a 'virtual smart
card' in TTCN-3 tets cases, primarily for testing remsim-bankd at
this point.

Harald Welte 0db4413ff6 stp: Introduce STP_Tests*.ttcn for testing OsmoSTP
In the past, we were automatically running [large parts of] the nplab
M3UA and SUA test suites, but those implement only a fraction of the

Let's introduce an initial set of STP tests with this patch.  We try
to not duplicate nplab here, and implement bits not covered there.

This test case is aimed to verify handling of both PTCCH/U and
PTCCH/D logical channels, recently implemented in [1]. This is
done by sending 16 Access Bursts on PTCCH/U, and then by
sending a random data block on PTCCH/D.

The existing TC_pcu_data_req_ptcch does not cover PTCCH/U, and
moreover involves TBF handling which has nothing to do with
PTCCH. Let's keep it anyway.

Vadim Yanitskiy f7d9c0f22b Introduce PCUIF, BTS and ClckGen components for RAW PCU test cases
The problem of existing test cases is that they mix IUT (i.e. OsmoPCU)
with OsmoBTS (osmo-bts-virtual) and OsmocomBB (virt_phy). This approach
allows to avoid dealing with TDMA clock indications and RTS requests on
the PCU interface - this is done by OsmoBTS. On the other hand, our test
scenarios may be potentially affected by undiscovered bugs in OsmoBTS
and the virt_phy.

In order to solve that problem, this change introduces a set of new
components and the corresponding handler functions:

  - RAW_PCUIF_CT / f_PCUIF_CT_handler() - PCU interface (UNIX domain socket)
    handler. Creates a server listening for incoming connections on a given
    'pcu_sock_path', handles connection establishment and message forwarding
    between connected BTS components (see below) and OsmoPCU.

  - RAW_PCU_BTS_CT / f_BTS_CT_handler() - represents a single BTS entity,
    connected to OsmoPCU through the RAW_PCUIF_CT. Takes care about sending
    System Information 13 to OsmoPCU, forwarding TDMA clock indications from
    a dedicated ClckGen component (see below), and filtering the received
    messages by the BTS number. Implements minimalistic scheduler for both
    DATA.ind and RTS.req messages, so they are send in accordance with the
    current TDMA frame number.

  - RAW_PCU_ClckGen_CT / f_ClckGen_CT_handler() - TDMA frame clock counter
    built on top of a timer. Sends clock indications to the BTS component.

All components communicate using TTCN-3 ports and explicitly defined sets
of messages (see RAW_PCU_MSG_PT). One noticeable kind of such messages is
events (see RAW_PCU_Event and RAW_PCU_EventType). That's how e.g. the PCUIF
component can notify the BTS component that OsmoPCU has just connected, or
the BTS component can notify the MTC that SI13 negotiation is completed.
Events may optionally have parameters (e.g. frame-number for TDMA_EV_*).

Furthermore, the proposed set of components allows to have more than one
BTS entity, so we can also test multi-BTS operation in the future.

Vadim Yanitskiy 7091e8de88 library/GSM_RR_Types.ttcn: refactor IaRestOctHH coding
According to 3GPP TS 44.018, section 10.5.2.16, IA Rest Octets IE
starting with 'HH' bits may contain one of the following CSN.1
encoded components:

  7 6 5 4 3 2 1 0  Bit Numbers
  H H 0 0 . . . .  Packet Uplink Assignment
  H H 0 1 . . . .  Packet Downlink Assignment
  H H 1 . . . . .  Second Part Packet Assignment

We already have (partial) support for the first two, while the
last type has not been supported so far. Let's add it.

Also, this change introduces several templates for IA Rest Octets
IE and some of its components mentioned above. This would allow
us to abstract the API users from dealing with further changes,
e.g. adding a coding attribute 'CSN.1 L/H' and missing fields.

Vadim Yanitskiy a4aacc2179 library/GSM_RR_Types.ttcn: fix: apply '2B'O padding to GsmRrMessage
For some reason TITAN starts padding not from the beginning of
record ImmediateAssignment, but from it's wrapper GsmRrMessage.
As a result, dec_GsmRrMessage() warns about undecoded octets:

  Data remained at the end of the stream after successful decoding '2B2B2B'O

Similarly enc_GsmRrMessage() generates a shorter payload. Let's
work this around by applying PADDING attribute to GsmRrMessage.

Vadim Yanitskiy 9b2a3e8cb8 library/GSM_RR_Types.ttcn: fix ImmediateAssignment coding regressions
Since I403d2141536303a966be7ff51b06c3de202412e6, IA Rest Octets is
a mandatory IE. When changing the definition of ts_IMM_ASS, I forgot
to mark its optional 'lh', 'hl', and 'hh' as omitted explicitly.

As a result, many of our TTCN-3 test cases were broken:

  Dynamic test case error: Using an unbound optional field.

Also, in Ifdcdcf50709fcc03195cb8ef6092977e26f910ec I added an
optional field 'pad' to record 'IaRestOctets'. That was not the
best solution, because padding should be handled transparently.

Let's get rid of that dummy field and equip both 'ImmediateAssignment'
and 'IaRestOctets' records with proper padding attributes. The later
one needs to be marked with 'CSN.1 L/H' attribute in the future, but
for now we should keep it octet-aligned.

Harald Welte 187f7a99c1 bsc: Test that ETWS Primary Notification are sent via dedicated channels
When the BSC receives an ETWS PN via CBSP, it must send it through all
established dedicated channels of the matching BTSs.

Harald Welte 11b734cb10 bts: Test if BTS forwards ETWS Primary Notification to PCU
All MS/UE must be notified of ETWS Primary Notifiations.

Depending on their state, the notification goes different paths:
* CS dedicated mode: BSC sends it as L3 message over LAPDm / DCCH
* CS/PS idle mode: BTS sends paging messages on PCH
* PS TBF active: PCU send Packet Application Info

This tests the last of the three methods by checking that a  ETWS Primary
Notification sent on RSL to the BTS is received by the PCU socket.

Vadim Yanitskiy 1f4486cfe3 library/GSM_RR_Types.ttcn: fix: IA Rest Octets may have optional padding
According to 3GPP TS 04.08 (version 7.21.0), section 10.5.2.16 and
table 10.5.45, IA Rest Octets IE may contain spare bits. Let's add
an optional field 'pad' to record 'IaRestOctets'.

NOTE: somehow this change crashes my TITAN runtime:

  dec_GsmRrMessage(): Stream before decoding: '2D063F100FE3673A096B0000C800300B2B2B2B2B2B2B2B'O

Vadim Yanitskiy dd6d5d1baa library/PCUIF_Types.ttcn: inform RAW codec about PADDING in PCUIF_data
PADDING is one of the TITAN specific language extensions [1], which
tells the RAW codec that an encoded payload shall end at a boundary
fixed by a multiple of 'padding' unit bits counted from the
beginning of the message.

Let's use it for record 'PCUIF_data', where the fixed-size buffer
is located in between the other fields, so padding will be ignored
by the RAW coding after decoding:

  $HOST: dec_PCUIF_Message(): Decoded @PCUIF_Types.PCUIF_Message: {
    msg_type := PCU_IF_MSG_DATA_REQ (0),
    bts_nr := 0, spare := '0000'O,
    u := {
      data_req := {
        sapi := PCU_IF_SAPI_AGCH (2),
	len := 23,
	data := '2D063F100FE3673A096B0000C800300B2B2B2B2B2B2B2B',
	...
      }
    }
  }

As a result, we don't have to deal with padding manually and
can safely use 'decmatch' statement in the receive templates.

In this testsuite, we simulate BTS and CBC by attaching to RSL and CBSP
protocol interfaces of the BSC.  We then issue a variety of CBSP
commands to the BSC and check for corresponding action on both the BTS-
facing RSL as well as responses on the CBSP side.

For some reason, the 'ifpresent' annotation doesn't work in lists

structure at some point.  However, this would be a significant detour
and I'd rather have working tests right now, so we can verify the
actual functionality merged into the BSC right now.

Oliver Smith aac9b9ceca BSSGP_Emulation: add BssgpDecodeDepth
Make the decoding level (BSSGP, LLC, SNDCP, L3) configurable, so the
existing PCU tests, that expect messages only decoded to the BSSGP
level, can pass again. Move the SNDCP decoding in f_dec_bssgp above the
L3 decoding, so f_dec_bssgp goes through the layers in the reverse order
of f_send_bssgp_dec.

I have verified, that all testsuites using the BSSGP Emulation (SGSN,
PCU, PCU-SNS) are still working with this patch.
